Generally, the methods include the u of a capillary tube made of a thermally conductive wall material and a thin wall such that the ratio of the thermal conductivity of the wall material to the wall thickness is at least
1,000-500,000. The solution is then expod to temperatures equal to or less than −80°C. and the vitrification solution containing the mammalian cells is cooled at a rate equal to or greater than 30,000-100,000,000° C./minute. The exposure of the capillary tube with a thermally conductive and thin wall allows for vitrification of the solution in the abnce of ice formation. Cryoprotectants can also be added to the vitrification solution to further prevent ice formation.
